Assume 50kg of mass are placed on the pan of a spring balance located on a freight elevator; local gravity acceleration is 9.7 m/s2. (a) When elevator is moving with an upward acceleration of 2.5 m/s2, what will the balance read? (b) If the elevator stopped, what will the balance read? (c) If the supporting cable breaks (elevator falls freely), what will the balance read? (d) If the balance reads 350 N, what are the circumstances?
